anterior interosseous nerve studies

The anterior interosseous nerve is a motor branch of the median nerve which supplies muscles in the forearm such as the pronator quadratus (PQ) and flexor pollicis longus (FPL) muscles. Many authors developed nerve conduction techniques in order to study the functional integrity of this motor branch, and even to make diagnosis of carpal tunnel syndrome (CTS) comparing the compound muscle action potentials from the abductor pollicis brevis (APB) and PQ muscles, innervated by the median and anterior interosseous nerves, respectively.
